Radial bearing i.e. cylindrical roller bearing, for use in e.g. wind power plant, has retainer arranged between rings for guiding rolling units, and drive units arranged in boards for movement of lubricant during rotating motion of bearing

摘要

The bearing (1) has a retainer (4) arranged between an outer ring (2) and an inner ring (3) for guiding rolling units (5), and a lubricant e.g. gear oil, provided in a lubricant area between the outer ring and the inner ring. An interior board (6), external boards and inner ring boards extend radially inwards and/or outwards to the outer ring and/or the inner ring. Drive units e.g. turbine blade shaped drive units, are arranged in the boards of the outer and inner rings for movement of the lubricant during rotating motion of the bearing.
